Authors: Mokrani Zahra, Oubelaid Adel, Rekioua Djamila, Serir Chafia, Kakouche Khoudir, Rekioua Toufik, Belhoul Talit

Abstract:

In this paper, a hybrid approach combining fuzzy logic-based Maximum Power Point Tracking (MPPT) with a battery-supercapacitor system is proposed to improve photovoltaic system performance. This method increases overall efficiency and extends the lifespan of the energy storage components. By optimizing energy capture and management, the system becomes more adaptive, reliable, and effective in harnessing solar power. The integration of fuzzy logic and hybrid storage represents a significant advancement in maximizing the potential of renewable energy technologies, providing a more sustainable and efficient solution for solar energy applications. This innovation enhances the effectiveness of solar power systems in real-world scenarios.

1 A Contribution to Blockchain Privacy

Authors: Malika Yaici, Feriel Lalaoui, Lydia Belhoul

Abstract:

As a new distributed point-to-point (P2P) technology, blockchain has become a very broad field of research, addressing various challenges, including privacy preserving, as is the case in all other technologies. In this work, a study of the existing solutions to the problems related to private life in general and in blockchains in particular is performed. User anonymity and transaction confidentiality are the two main challenges to the protection of privacy in blockchains. Mixing mechanisms and cryptographic solutions respond to this problem but remain subject to attacks and suffer from shortcomings. Taking into account these imperfections and the synthesis of our study, we present a mixing model without trusted third parties, based on group signatures, allowing reinforcing the anonymity of the users, the confidentiality of the transactions, with minimal turnaround time and without mixing costs.
